Target Earth (1954)

Giant robots from Venus launch an invasion on Chicago, leaving the city eerily deserted. Among the few survivors are Frank and Nora, the latter having recently survived a suicide attempt. Their chance meeting with a jubilant couple, Vicki Harris and Jim Wilson, offers a glimmer of hope. Together, they evade the relentless robot patrol and seek shelter in a sprawling hotel. However, their sanctuary soon transforms into a nightmare as they confront a new threat: Davis, a dangerously unstable murderer lurking in the shadows.
